PORTABLE REFRlGERATlNG-COVER.

SPECIFICATION forming part of Letters Patent No. 238,307, dated March 1, 1881.

Application filed June 12, 1880. (No model.)

To all whom it may concern:

Be it known that I, ALFRED G. PEcoR, of Baltimore, in the county of Baltimore and State of Maryland, have invented a new and useful Improvement in Portable Refrigeratin g- Govers; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is a device adapted to the special purpose of conveniently keeping butter and like perishable articles, when displayed upon the slab or table for sale in the market, cool and firm.

It consists of a glazed cover of a shape adapted to be placed over the dish containing the butter, and having in the top thereof an ice-box provided with a cover, and adapted to contain the ice.

In the accompanying drawings, Figure 1 is a perspective View of my invention, and Fig. 2 a longitudinal central section.

The cover is made of frame-work a a b b, which should be as light as it can be made without sacrifice of strength. Into these frames I place, preferably upon three sides, panes of glass, which should be fitted closely in place in order to make the cover as tight as possible. E

On the top of the cover I form a case, A. The outside of the case may be formed of thin boards. The inside I make preferably of zinc.

The inside box is represented at c. I prefer to make it separable, and a very simple and efficient form of the box may be made by turning out the flanges, as shown at cl 61, so that they can bear upon the rabbeted edges 0 e of the sides of the wooden case.

If preferred, the inner box may be made somewhat smaller than the inner dimensions of the outer case, so as to leave an air-space between the two, thereby rendering it the better non-conductor of heat.

The cover D, which may be lined with tin or zinc, and made suitably non-conducting, is placed over the ice-box, and may be provided with a knob, g, or any suitable handle. One end of the cover is provided with a wooden door for convenience of removing the articles Upon the the glass may be conveniently raised. The object of this is to permit customers on the outside of the table or bench to have access to the interior of the case, when it is desirable to permit them totastc theiarticle.

Manifestly, the cover may be made with double glass walls, and may be rectangular or polygonal, or of any shape that may be desired.

When not in use the cover may be lifted off and put away without disturbing the articles. For convenience in handling, it is provided with bails k k. r

The case may be made of wood, metal, or other suitable material, as may be found convenient.

This device is intended principally as a cover for preserving butter and similar perishable articles in market-stalls, &c.; but it is also adapted, without material change of construction, 'for household use, for the same purposes, and in any situation where a refrigeratingcover is necessary.

I am aware that a refrigerating-cover having opaque sides and open bottom, an ice-box, and means'for letting oif the drip-water is patented; but such device cannot be used to exssl hibit perishable articles, which are at the same time kept in a state of preservation.

I am also aware of the common useof hinged sliding-doors in refrigerators, bee-hives, and other structures, and do not claim such as forming, by themselves, an invention of my own.

Having thus described my invention, what I claim is- 1. In the described cover having the lower glazed part and closed box in the top, the sliding and hinged doors, substantially as described.

2. A portable case for exhibiting perishable articles, consisting of a box or case having open bottom and transparent faces, and provided with a receptacle for containing ice, whereby the goods while being exposed to view are preserved, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALFRED O. PEOOR.
